# Moral development (Kohlberg)

- Theory

Kohlberg proposed that moral reasoning grows from avoiding punishment, to following social rules, to universal principles; Gilligan added an ethic of care.

Updated Nov 5, 2026

## Key points

- Preconventional (most children under about 9): avoiding punishment, then seeking reward or fair exchange.
- Conventional (from late childhood and adolescence, most adults): being a good person in others' eyes, then law and order.
- Postconventional (reached by few adults): social contract and individual rights, then universal ethical principles.
- What is scored is the reasoning behind the answer, not the answer itself.
- Gilligan: an ethic of care (relationships, responsibility) alongside Kohlberg's ethic of justice; she argued women were wrongly scored lower.
- Critiques: cultural bias toward Western individualism, and moral reasoning does not reliably predict moral behavior.

## What it is

Building on Piaget, Lawrence Kohlberg studied how people reason about moral dilemmas, such as whether a man should steal a drug he cannot afford to save his wife (the Heinz dilemma). He scored the reasoning, not the answer, and described three levels with two stages each. Carol Gilligan criticized the model for being based on male participants and for valuing justice over care and relationships; other critiques note cultural bias and that reasoning does not reliably predict behavior.

## Key facts

- Piaget described an earlier shift from heteronomous morality (rules fixed by authority, judged by consequences) to autonomous morality (rules by agreement, judged by intentions).
- Moral reasoning depends on cognitive development and on perspective-taking.
- Moral emotions such as empathy, guilt and shame develop alongside reasoning.
- Later research found care-based and justice-based reasoning in both sexes, depending more on the type of dilemma than on gender.

## Kohlberg's levels and stages

| Level | Stage | What makes an act right | Example of reasoning |
| --- | --- | --- | --- |
| Preconventional | 1. Obedience and punishment | Avoiding punishment | He should not take the bicycle because he will be grounded |
| Preconventional | 2. Self-interest and exchange | Getting a reward or a fair deal | Share the sweets so the friend shares next time |
| Conventional | 3. Good relationships | Being seen as a good person | Help the classmate so the teacher thinks well of her |
| Conventional | 4. Law and social order | Doing one's duty and obeying rules | Rules are rules, or everything falls apart |
| Postconventional | 5. Social contract and rights | Rules serve people and can be changed by agreement | An unfair rule should be changed by voting |
| Postconventional | 6. Universal principles | Justice and dignity for everyone | A life is worth more than property, whoever owns it |

## Clinical notes

- Explaining rules to children at their level (consequences for young children, fairness and relationships for older ones) improves cooperation.
- Persistent disregard for others' rights and lack of remorse in a child is a behavioral problem to evaluate, not just a stage.

## Test yourself

Think of the answer, then tap the question to see it.

## What did Kohlberg score when he presented the Heinz dilemma?

The reasoning behind the answer, not whether the person said Heinz should steal or not.

## At which Kohlberg level is reasoning based on law and order?

The conventional level (stage 4).

## What was Gilligan's main critique of Kohlberg?

That the model was built on male participants and valued justice over an ethic of care and relationships, unfairly scoring many women lower.

## Does moral reasoning predict moral behavior well?

Not reliably; people often reason at one level and act differently, which is a major critique of the model.
